Thomas Aquinas made the impossibility of infinite regress arguments for God. Science found that to be true in the last century.

Democracy is not so much an issue. It basically means universal suffrage which is not a problem. The problem is civil government. It's an oxymoron. Every government, every state, that was ever created was created by military. Military is the government, it is the state.
In that sense, civil government is just an extended arm of the military, it's a mirage, an induced perception of peaceful government which is held by the hidden military. Universal suffrage should be used to control military because that is the main source of power. Right now, there is no direct democratic link between the miltary and the people.
Then when you scratch the surface, military is financed by the financiers. Financiers and military are not directly linked to democracy, and that is the problem of our democracy since French revolution. People never really got free.
